Grinding Circumfrential Seem Flush
Grinding Circumfrential Seem Flush
(OP)
I have an ASME VIII, Div 2 Part 5 design by analysis vessel. For a number of reasons I am required to weld a support saddle on top of the circular seem (RT1 full radiograph). The wall thickness is 3.5 inches, so the seem is fairly wide.
My question is:
1.) Are there any ASME code violations with grinding the circumferential seem flush to accommodate welding the saddle on the vessel?
2.) I am assuming I would need to radiograph the seem after girding it flush if allowed, right?
Thank you for your help in advance.

The outside weld (probably a fillet weld joining the support to the PV), will be in the way of a post-attachment RT exam. Do the pressure weld RT before the next weld outside goes over it.
